It's still an active IP, and the only USB 2.0 (host, device, otg)
controller we have currently in Faraday.

It's used in upcoming Faraday A369 SoC patch set (I'm still waiting
for the dependant NAND driver: ftnandc021 to be commited),

and the new SoC platforms (For politics reason,  they won't be
released by myself.) in year 2013.
